The veins that irrigate leaves during photosynthesis are demonstrated to be strikingly more abundant in flowering plants than in any other vascular plant lineage. Angiosperm vein densities average 8 mm of vein per mm(-2) of leaf area and can reach 25 mm mm(-2), whereas such high densities are absent from all other plants, living or extinct.
